129 if with craft different if serving as divisional principle, decompression destilling tower can be divided for lube model with two kinds of fuel groovy types. No matter be,plant to where decompression destilling tower, the working requirement that place should achieve is same, where is that both and particular distinguishing feature respectively?
When the user is using decompression destilling tower, hope to be able to have as far as possible high separate out rate, reduce heat up in a steamer to assign oily incomplete charcoal value and heavy metal content thereby, use at preparation lube to perhaps regard cracking as raw material.
As we have learned, of craft of lube decompression distill apply, it is to be follow-up lube to produce device to provide raw material, so the actor bad of effect of fractional distillation of lube decompression destilling tower will affect the quality of its follow-up treatment process and lube product directly.
From distillation process itself for, it is good that to the quality of lubricant oil plants the requirement basically included suddenly to spend charcoal of appropriate, incomplete to be worth low, chroma, range of Cheng of heat up in a steamer is narrow wait, accordingly the requirement of its fractional accuracy and crude oil often press destilling tower similar.
Divide the opposite volatility between considering the heat up in a steamer below the circumstance in decompression the conference is bigger, using board type tower so dish when need to use inside decompression tower bigger board span, this also is the tray number between cent of two sidetrack heat up in a steamer less than atmospheric tower main reason. General 3 can satisfy a requirement to 5 tray.
With often press destilling tower photograph to compare, the affirmatory method of condition of each bits of temperature in decompression distill also is identical, only inside the function that circumfluence controls to oil gas cent decides harder, because this is in engineering design, its temperature condition should press corresponding means to have consideration.
If can accurate computation gives the loop inside decompression destilling tower to separate the function that control to oil gas, with respect to each temperature of destilling tower of decompression of can sufficient control, make its maintain the foundation that is helpful for distillation craft in to go up, make the work efficiency of decompression destilling tower can have rise apparently.
